Nutrition plays a vital role in maintaining healthy eyes throughout life. Vitamins A, C, and E help protect corneal and retinal cells from damage, while zinc supports night vision and overall retinal health. Omega-3 fatty acids, found in fatty fish and flaxseeds, contribute to tear production and may reduce dry eye symptoms. Lutein and zeaxanthin, present in leafy green vegetables, help filter harmful blue light and lower the risk of age-related macular degeneration. A balanced diet rich in fruits, vegetables, whole grains, and healthy fats supports clear vision and long-term eye health. Regular hydration and limiting processed foods further protect visual performance.
